Voyage plans have always been a requirement under the International Maritime Organization's SOLAS conventions, however consistency and level of detail in the plans was previously not detailed in the formal polices. The new language, adopted by CLIA and ECC, explicitly requires for the plan to be "drafted by a designated officer and approved by the master" well in advance of the sailing, Recall that the master of Costa Concordia claims that he was authorized to do the "sail by salute".
The change in life jacket policy calls for ships to carry more life jackets than are currently legally required. SOLAS currently dictates that ships carry life jackets for every berth, which may be higher than the number of persons onboard, plus five percent. In practice, the majority of cruise ships carry many more life jackets than is required, but the new policy will raise the official mandatory minimum.
Some Concordia passengers indicated that they had to return to the cabins in the dark in order to retrieve their life jackets. The new limits will mean the muster stations will be required to increase the quantities available for passengers unable to return to their cabins in an emergency to retrieve their life jackets.
